The time isnt the issue. The non-repair is. I have the old '70s model 1894. love it. Maybe i will take the firing pin out of the Rossi and hang it over the mantle.. more useful that shooting it.
BTW: I tried the Laser Cast .431 RNFPs in my Marlin. Tighter group at 50 yards. I heard they work better in Marlins. http://www.laser-cast.com/44Cal.html
